✨ Major updates

### Added

- AGENTS.md
- **Dependency Tags Support**: Added `spec/support/dependency_tags.rb` to load shared
  dependency tags from tree_haver and ast-merge. This enables automatic exclusion of
  tests when required backends or dependencies are not available.
  - Tests tagged with `:ffi_backend`, `:java_backend`, `:rust_backend` are now properly
    excluded when those backends aren't available
  - Tests tagged with `:rbs_grammar` are excluded when tree-sitter-rbs isn't available
  - Tests tagged with `:rbs_parsing` work with any available RBS parsing backend
- FFI backend isolation for test suite
  - Added `bin/rspec-ffi` script to run FFI specs in isolation (before MRI backend loads)
  - Added `spec/spec_ffi_helper.rb` for FFI-specific test configuration
  - Updated Rakefile with `ffi_specs` and `remaining_specs` tasks
  - The `:test` task now runs FFI specs first, then remaining specs
- **BackendRegistry Integration**: RbsBackend now registers its availability checker with `TreeHaver::BackendRegistry`
  - Enables `TreeHaver::RSpec::DependencyTags` to detect RBS backend availability without hardcoded checks
  - Called automatically when backend is loaded: `TreeHaver::BackendRegistry.register_availability_checker(:rbs)`

### Changed

- appraisal2 v3.0.6
- kettle-test v1.0.10
- stone_checksums v1.0.3
- [ast-merge v4.0.6](https://github.com/kettle-rb/ast-merge/releases/tag/v4.0.6)
- [tree_haver v5.0.5](https://github.com/kettle-rb/tree_haver/releases/tag/v5.0.5)
- tree_stump v0.2.0
  - fork no longer required, updates all applied upstream
- **RbsBackend refactored to use TreeHaver::Base classes**
  - `RbsBackend::Language` now inherits from `TreeHaver::Base::Language`
  - `RbsBackend::Parser` now inherits from `TreeHaver::Base::Parser`
  - `RbsBackend::Tree` now inherits from `TreeHaver::Base::Tree`
  - `RbsBackend::Node` now inherits from `TreeHaver::Base::Node`
  - Consistent API across all merge gem backends
- **Tree-sitter grammar registration** - `register_backend!` now registers both:
  - The RBS gem backend (Ruby-based parser, MRI only)
  - The tree-sitter-rbs grammar path (for native tree-sitter backends)
  - This enables `TreeHaver.parser_for(:rbs)` to use tree-sitter when available

### Fixed

- ConflictResolver now applies Hash-based per-node-type preferences via `node_typing`.
